SECTION 4. FIRST-AID MEASURES First-aid Measures Inhalation Move to fresh air. If breathing is difficult, trained personnel should administer emergency oxygen if advised to do so by Poison Centre or doctor. Immediately call a Poison Centre or doctor. Skin Contact Immediately rinse with lukewarm, gently flowing water for 15-20 minutes. Immediately call a Poison Centre or doctor. Eye Contact Immediately rinse the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. Contact physician immediately. Ingestion Do not induce vomiting. Immediately call a Poison Centre or doctor. First-aid Comments Immediate medical attention is required. Provide general supportive measures (comfort, warmth, rest). Do not leave the victim unattended. Most Important Symptoms and Effects, Acute and Delayed For most important symptoms and effects (acute and delayed), see Section 2 (Hazard Identification) and Section 11 (Toxicological Information) of this SDS. Immediate Medical Attention and Special Treatment Special Instructions General advice, consult a physician. Show this safety data sheet to the doctor in attendance. Move out of dangerous area.

SECTION 5. FIRE-FIGHTING MEASURES Extinguishing Media Suitable Extinguishing Media Not combustible. Use extinguishing agent suitable for surrounding fire. Carbon dioxide, dry chemical powder or appropriate foam. Unsuitable Extinguishing Media Water. Specific Hazards Arising from the Product Reacts violently with water and organic materials with the evolution of heat. Contact with water liberates toxic gas. Heating increases the release of toxic vapour. Closed containers may rupture violently when heated releasing contents. In a fire, the following hazardous materials may be generated: corrosive hydrogen chloride. Hydrogen Iodide.

Contact with water liberates toxic gas. Heating increases the release of toxic vapour. Closed containers may rupture violently when heated releasing contents. In a fire, the following hazardous materials may be generated: corrosive hydrogen chloride. Hydrogen Iodide. Special Protective Equipment and Precautions for Fire-fighters As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Chemical protective clothing (e.g. chemical splash suit) and positive pressure SCBA may be necessary.

SECTION 6. ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment, and Emergency Procedures Use the personal protective equipment recommended in Section 8 of this safety data sheet. Increase ventilation to area or move leaking container to a well-ventilated and secure area. Remove or isolate incompatible materials as well as other hazardous materials. Environmental Precautions Do not allow into any sewer, on the ground or into any waterway. Methods and Materials for Containment and Cleaning Up Avoid generating dust. Collect using shovel/scoop or approved HEPA vacuum and place in a suitable container for disposal.

SECTION 7. HANDLING AND STORAGE Precautions for Safe Handling Wear personal protective equipment to avoid direct contact with this chemical. Avoid generating dusts. Only use where there is adequate ventilation. Prevent accidental contact with incompatible chemicals. Keep containers tightly closed when not in use or empty. Conditions for Safe Storage Store in an area that is: cool, dry, well-ventilated, separate from incompatible materials (see Section 10: Stability and Reactivity). Protect from conditions listed in Conditions to Avoid in Section 10 (Stability and Reactivity). Store in the original, labelled, shipping container.

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Control Parameters Not available. Consult local authorities for provincial exposure limits. Consult local authorities for state exposure limits. Appropriate Engineering Controls Use local exhaust ventilation and enclosure, if necessary, to control amount in the air. Provide eyewash and safety shower if contact or splash hazard exists. Individual Protection Measures Eye/Face Protection Wear chemical safety goggles and face shield when contact is possible. Skin Protection Wear chemical protective clothing e.g. gloves, aprons, boots. Suitable materials are: butyl rubber. Respiratory Protection Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
